| What a great science project, or something to just play around with. Everything is made of plastic except the optics and the bulbs. This is just a neat educational item to experiment and play with. Comes with a screw housing that attaches to the one end that slides out of the main projector housing. This screw housing is for focusing you projection lens. The lenses for this housing are 32mm diameter and fit in the specified area of the housing. One has a focal length of about 50mm and the other has a focal length of about 110mm. There is a plastic round press ring that you put behind the lens to keep it from falling out. At the other end of the projector housing is a hole for the light source. The housing fits snug in the hole. Out the back of the light source housing are two wire leads for power. The bulbs are 2.2VDC 25 Amps. Once these two items are put together everything else just slides into slots or stands inside the projector housing. Other items included are: 1 prism, 2 lamps, 1 candle, 1 small acrylic block, 2 green stands, 2 43mm long by 30mm wide mounted mirrors, 3 mirrors mounted on one plastic holder with a degree scale, 1 white plastic slot piece, 1 plastic diffusing filter, 1 spinning wheel with slits large circle small circle and an arrow, 1 spinning wheel with 5 animals and on the other side 5 plants, 1 slot mounted negative lens, 1 slot mounted positive lens, and 1 slot mounted empty. All you need is a 2.2VDC 0.25A power supply and you have your own projection system. Instructions are in Chinese! |
